Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram showing a structure of a demand / response management system based on renewable energy / ESS using EMG according to an embodiment.

As shown in FIG. 1, the demand / response management system based on renewable energy / ESS using the EMG according to the embodiment includes the DRMS 10, the power means, and the EMG 50.

The DRMS 10 provides and manages a demand response service to the customer in order to realize a reduction in power consumption of the customer. At this time, the DRMS 10 generates demand response information based on the power consumption information of the customer, and provides the demand response service to the customer based on the generated demand response information. Here, the demand response information may include a demand amount of power use reduction, an amount of actual demand reduction, a reduction participation rate, an actual reduction participation rate, and the like. In addition, the demand response service is a method for inducing a reduction in the electric power consumption of the consumer. In response to the payment of the incentive or the change of the electric charge by the time zone, the consumer shifts the consumption pattern of the electric consumption of the consumer out of the normal consumption pattern .

The power means is an energy supply source for supplying energy, including a renewable energy generation module and an ESS 33, and also supplies power to a customer including a main power supply unit not shown.

The main power supply unit includes a power plant that generates electric power through thermal power generation, nuclear power generation, or hydroelectric power generation, a power station including a power station and a substation, and a power station sends power to the power station through a transmission line, .

The renewable energy generation module may be, for example, a photovoltaic power generation (PV) unit 31 for generating electricity using solar energy among renewable energy sources.

The ESS 33 is a facility for charging the battery 333 from the PV 31 or the main power supply unit to store the energy and discharging the battery 333 to supply the stored energy to the host. A Power Conditioning System) 331, a battery 333, and a battery management system (BMS) 335.

The consumer may be, for example, a home, a building, an office space, a small factory facility, and the like. Here, in order to provide a stable power supply to the customer, a small-sized EES can be intensively arranged in a portion where the energy consumption of the customer is large. For example, if the energy consumption of each layer in a building is different, more energy-consuming layers can place more small- and medium-sized EESs than lower-energy layers.

In addition, the customer can establish a network. Here, if the network is a home network, it may be a home network constructed by including a plurality of household appliances and communication networks, which are power consumption appliances.

In order to participate in the demand response service provided by the DRMS 10, the customer transmits the power usage information of the network constructed by the customer (hereinafter referred to as 'build network') to the DRMS 10 through the EMG 50 .

The power usage information includes metering information collected from the smart meter 110 installed in each of the users, including power consumption information, reduction capacity information, and the like. Here, the smart meter 110 is a device that can remotely check power consumption.

The reduction capacity information includes a total demand reduction amount, a demand reduction available capacity, a demand reduction actual usable capacity, and the like, which are calculated using the EMG installed in the home.

The EMG 50 is installed in each customer and is connected to the DRMS 10 through the first communication network and to the smart meter 110 through the second communication network. Here, the first communication network may be, for example, the Internet (I), and the second communication network may be, for example, Power Line Communication (PLC).

The EMG 50 receives the demand response information of the generated DRMS 10 by grasping the situation of the electric power consumption of each customer in order to make the PV 31 and the ESS 33 demand reaction, And controls the power generation of the PV 31 and the charging and discharging of the ESS 33 according to the situation of each customer. Here, the demand response resource is a resource for providing power by considering the power consumption of the customer and realizing reduction of power consumption of the customer through the power supply.

For example, the EMG 50 receives demand response information from the DRMS 10, periodically collects the metering information from the smart meter 110, and receives information about the battery 333 from the ESS 33 PV 31 and then determines the operation mode of the ESS 33 based on the demand reaction information, the metering information, the information about the battery 333 and the PV 31 to generate the ESS 33 And controls the PV 31 and the ESS 33 in the determined operation mode. Here, the operation mode may be a charge mode, a discharge mode, a power generation mode, or the like.

Hereinafter, a demand response management type for demanding and reactivating the PV 31 and the ESS 33 will be described in detail, for example.

The demand response management type for making the PV 31 and the ESS 33 demand reaction can be various according to the VEN (Virtual End Node) which is a lower node and VTN (Virtual Top Node) which is an upper node that manages the VEN have.

FIG. 2 is a diagram showing VEN and VTN for demand response and resource conversion of PV and ESS in FIG. 1; FIG. As shown in FIG. 2, the VEN is a lower EMG installed in one or more customers, and the VTN may be one or more DRMS 10 and may also be a parent EMG having a lower EMG to be managed. Here, the upper EMG is VTN for the lower EMG and VEN for VTN.

FIG. 3 is a diagram illustrating a demand response management type for reacting PV and ESS of FIG. 1 to demand response resources. One demand response management type may be composed of one ESS 33 and one VTN for home and home demand demand management as the VEN.

That is, as shown in FIG. 3, the DRMS 10 may be used as the VTN. The PV 31 and the ESS 33 are installed in the home and the EMG 50 and the smart meter 110 are installed in the home. Here, the home may be supplied with power from the main power supply unit.

FIG. 4 is a diagram illustrating another type of demand response management for reacting PV and ESS of FIG. 1 to demand response resources. In addition, another demand response management type is a case where a plurality of ESSs 33 are configured, one or more lower EMGs as the VEN, one upper EMG 50A for demand response management of the lower EMG, And a VTN for management of the terminal 50A. Here, the upper EMG 50A is VTN for the lower EMG and VEN for the VTN.

That is, as shown in FIG. 4 (a), the DRMS 10 may be used as the VTN. The upper EMG 50A is a VTN for each home that is one or more lower EMGs and at the same time becomes a VEN for the DRMS 10 and is installed in a predetermined area outside the home . The PV 31 and the ESS 33 are installed in each home and the EMG 50 and the smart meter 110 are installed in each home. Here, each of the homes may be supplied with power from the main power supply unit.

Also, as shown in FIG. 4 (b), the DRMS 10 may be used as the VTN. The upper EMG 50A is one or more lower EMGs, which are VTNs for the respective layers in the building and become VENs for the DRMS 10, and may be installed at a predetermined site outside the building. A PV 31 is installed in the building, and an ESS 33, an EMG 50, and a smart meter 110 are installed in the respective layers of the building. Here, the building may receive power from the main power supply unit.

Hereinafter, a method of managing demand and response based on renewable energy / ESS using EMG according to an embodiment will be described in detail.

FIG. 5 is a flowchart illustrating a method for managing demand / response based on renewable energy / ESS using EMG according to an embodiment.

As shown in FIG. 5, the demand response management method when the EMG 50 installed in each of one or more customers as VEN and one or more VTNs for demand response management of the customer is as follows. Here, the VTN may be a DRM 10 or an upper EMG 50A having a lower EMG to be managed.

First, the EMG 50 installed in each of the above-mentioned cafeterias includes metering information collected from the smart meter 110, power generation of the PV 31 collected from the ESS 33, and status information on charging and discharging of the battery 333 Determines and determines the operation mode of the ESS 33 through the collected information, and then outputs the mode of operation of the determined ESS 33 to the ESS 33, that is, outputs the mode. Here, the operation mode of the EES 33 may be a charge mode, a discharge mode, and a power generation mode.

Then, the EMG 50 transmits power usage information including the metering information to the DRMS 10. The DRMS 10 generates demand response information including a requested amount of power use reduction based on the received power usage information to provide a demand response service to the customer so as to realize power consumption reduction of the customer.

The EMG 50 then receives the demand response information from one or more DRMSs 10 in step S100 and includes the power usage information, the charge status information of the ESS 33, The power use reduction possible amount is calculated based on the demand response resource state information (S110).

That is, the EMG 50 can calculate the power use reduction amount by analyzing the relationship between the size of the amount of the demand reaction resource reducible amount and the demand response service participation loyalty according to the following Equation 1-2.

[Equation 1]

으로 산출된다.)(n is the number of EMGs 50 having a high loyalty to the demand reaction service among the EMGs 50 registered in the DRMS 10 and α is a value of 1.0 to 0.8 for the loyalty participating demand response service, _{The i-th} reducible amount is calculated as the average of the unit time demand reductions of the EMG _i (past) × the demand times of the reductions, and the average of the unit demand reductions of the EMG _i is

.

&Quot; (2) "

(m is the number of EMGs (50) reporting a reduction of 70% or less of the reduction quota in past demand reductions, and β is a weighted value of 0.7 to 0.5 for loyalty to demand response services.)

Subsequently, the EMG 50 compares the amount of power reduction use request with the amount of power use reduction request amount, that is, whether or not the target reduction amount is achieved (S120), and transmits demand reaction service participation information to the DRMS 10 according to the determination.

If the target amount of reduction can not be achieved because the amount of power use reduction is smaller than the amount of power use reduction requested amount, the EMG 50 transmits a message of non-participation to the DRMS 10 at step S130. On the other hand, if the power use reduction possible amount is larger than the power use reduction requested amount and the target reduction amount can be achieved, it is determined whether the VEN is the upper EMG 50A having the lower EMG to be managed (S140).

At this time, when the VEN is the upper EMG 50A, the upper EMG 50A allocates a reduction target amount for each lower EMG, and transmits demand response information including the allocated reduction target amount to the lower EMG (S150).

Since the upper EMG 50A includes one or more lower EMGs to be managed, in order to achieve the target reduction amount based on the power use reduction request amount of the demand response information received from the DRMS 10, The target amount should be divided and allocated.

In order to allocate a reduction target amount to each of the lower EMGs, the upper EMG 50A calculates a reduction target amount of each lower EMG as follows.

That is, when each of the lower EMGs satisfies the discrimination formula (power use reduction amount> reduction target amount), the upper EMG 50A can reduce the reduction target amount to the size of the individual reducible amount To be proportionate, a reduction target should be allocated to each of the lower EMGs.

이 된다.In order to satisfy this requirement, it is assumed that the power utilization reduction potential of each of the lower EMGs is larger than the reduction target amount of each of the lower EMGs. The capacity ratio γ to be reduced by each lower EMG is calculated according to the reduction target amount =

.

Therefore, the reduction target amount of each of the lower EMGs is calculated as the unit time demand reduction amount of EMG _i x reduction request time x y.

Each of the lower EMGs receives demand reaction information from the upper EMG 50A (S100), and generates demand response information including power usage information, charge status information of the ESS 33, development status information of the PV 31, And calculates the power use reduction amount based on the state information.

Here, each of the lower EMGs can calculate the power use reduction amount by analyzing the relationship between the size of the amount of the demand reaction resource reducible amount and the demand reaction service participation loyalty in the same manner by Equation (1-2).

Each of the lower EMGs then determines whether or not the target reduction amount is achieved by comparing whether the target reduction amount of the reduction target amount is achieved, that is, by comparing the power use reduction possible amount with the reduction target amount through the calculated power use reduction amount, And transmits the response service participation information to the upper EMG 50A.

Subsequently, the upper EMG 50A receives and collects the available amount from each lower EMG (S160). Then, the upper EMG 50A compares whether the target reduction amount of the power use reduction request amount is achieved or not, that is, the sum of the available participation amount and the power use reduction request amount through the collected available amount, and determines whether the target reduction amount is achieved (S170 , And transmits the demand response service participation information to the DRMS 10 according to the determination.

At this time, if the total amount of participation is greater than the requested amount of power use reduction, the upper EMG 50A transmits a message of participation in the DRMS 10 (S180). If the power use reduction amount is larger than the power use reduction request amount and the target reduction amount can be achieved, it is determined whether the VEN is the upper EMG 50A having the lower EMG to be managed (S140). If there is no lower EMG 50 associated with the VEN, the demand response service participation message transmission process and the response message reception process are omitted in the lower EMG 50, and the EMG 50, which is the VEN, transmits the participation message to the DRMS 10 (S180).

Meanwhile, the upper EMG 50A transmits a message of non-participation to the DRMS 10 if the total amount of participation is less than the request amount of power use reduction and the target amount of reduction can not be achieved (S130).

The EMG 50 receives demand response information from the plurality of DRMSs 10 or the upper EMG 50A in all the steps of determining whether the EMG 50 participates in the demand reaction service in the above- , The EMG 50 may transmit a demand response service participation message to the DRMS 10 or the upper EMG 50A, which presents favorable requirements among them.

Subsequently, the EMG 50 that has transmitted the demand response service participation message participates in the demand response service (S190). Here, the EMG 50 outputs to the ESS 33 the operation mode and operation duration information of the ESS 33 corresponding to the demand reaction information of the demand reaction service decided to participate. The ESS 33 starts operation in the operation mode input from the EMG 50 and outputs the completion information to the EMG 50 when the operation is completed after the operation duration. At this time, the EMG 50 can control the PV 31 and the ESS 33 so that the PV 31 and the ESS 33 can make demand reaction resources. That is, the EMG 50 can control the operation mode and operation duration of the ESS 33 based on the demand response information. The EMG 50 receives the completion information of the ESS 33 and collects the metering information collected from the smart meter 110 to determine whether the demand response of the ESS 33 is met.

After the participation of the demand response service, the upper EMG 50A determines whether the demand response service time has elapsed (S200). If it is determined that the demand response service time has not elapsed, . On the other hand, if the demand response service time elapses, the result of the demand response service is transmitted to the DRMS 10 (S210).

As described above, the system and method for managing demand response based on new renewable energy / ESS using EMG according to the embodiment is characterized in that new and renewable energy and ESS are controlled by EMG installed in the customer, Since renewable energy and ESS can be linked to DRMS, it is possible to differentiate according to the various power consumption by individual customer, and energy efficiency can be improved by realizing reduction of power consumption of the customer.

In addition, the system and method for demand response management based on the renewable energy / ESS using EMG according to the embodiment is a system in which PV and ESS are reacted to demand response so that PV and ESS are linked to demand response, It is possible to make decisions in real time on the acceptance of demand response service, thereby improving the stability and commerciality of DRMS.

In addition, the system and method for demand response management based on the renewable energy / ESS using the EMG according to the embodiment can convert small and medium scale PV and EES into various customers such as small and medium sized buildings, In the case of installation, small and medium sized EES can be installed intensively in the portion where energy consumption is high in the customer, so that it is possible to effectively cope with the fluctuation of the power consumption, so that stable power supply can be provided to the customer.

In addition, the system and method for demand and response management based on renewable energy / ESS using EMG according to the embodiment enable electric power to be supplied to the customers efficiently by enabling stable supply of electric power by converting PV and ESS into demand reaction resources, System problems can be detected and the system can be operated efficiently.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various changes, modifications and substitutions are possible within the scope of the technical idea of the present invention.
